A Trixie is one of the older full-cover bets on the British book. Three picks, four lines, a unit stake on each — and a settlement that asks only that two of the three selections land. It looks like an accumulator with training wheels, but the arithmetic behind it is its own shape, and the shape changes what it costs the punter. This guide walks through that shape, the way the offer sits in the wider family of full-cover bets, and the ten UK-licensed bookmakers that take the bet today. The angle is the consequence: what the Trixie takes from the punter, what it gives back, and where the rules start to bite.

Currency stamped: data current as of 27 October 2026, checked against the Gambling Commission’s public register.

What the Trixie actually is — three picks, four bets

A Trixie is a multiple bet that bundles three selections into four separate wagers. Three of those are doubles (selection A combined with selection B, A with C, B with C) and the fourth is a treble (all three combined). The punter chooses a unit stake and that same stake is placed on every one of the four lines. The total outlay is the unit stake multiplied by four.

That four-line shape is the entire point of the bet. A standard accumulator rolls three picks into a single line; a Trixie splits them into the four multiple combinations and stakes them all. Two selections out of three winning still produce a payout, because the doubles that include those two winners settle as winning doubles. Three selections out of three winning produces a payout from the three doubles plus the treble. The bet settles for nothing only if two or more of the three selections lose.

The number four is not arbitrary. Three items, taken two at a time, give three pairs (AB, AC, BC) and one triple (ABC). That is the complete set of multi-leg combinations from a three-selection card, and the Trixie is the smallest full-cover bet the British book offers — a coverage that goes wider as the number of selections rises.

Reading the Trixie against its bigger cousins

A Trixie belongs to a wider family of full-cover bets, each one defined by how many selections it covers and which combinations it prices. The Patent is the next step up from a Trixie: same three selections, but it adds the three singles, taking the count from four bets to seven. The singles mean a Patent can settle for a return even when only one of the three picks wins, which the Trixie cannot.

Move to four selections and the family widens again. A Yankee is four picks, eleven bets — six doubles, four trebles and one fourfold. A Lucky 15 stretches the same four picks across fifteen bets by adding the four singles; Lucky 31 takes five selections to thirty-one bets, and Lucky 63 takes six to sixty-three. The Heinz is the six-selection, fifty-seven-bet cousin — twenty doubles, twenty trebles, fifteen fourfolds, six fivefolds and one sixfold. The Goliath, at eight selections and two hundred and forty-seven bets, sits at the top of the family and is a working bet for serious bet builders.

A Trixie is the family at its smallest. Three selections, four bets, no singles. The trade is clear: lower total stake than a Patent, but no payout unless at least two selections win. Anyone choosing between the two is choosing between two ways of pricing the same three picks. The Patent’s three extra lines raise the outlay by 75% and they pay back on weaker outcomes. The Trixie’s narrower line set costs less to enter but is also a stricter test.

How the settlement works, line by line

The settlement is straightforward in the winning case. Take a Trixie at a unit stake of £1 on three selections priced at decimal odds of 2.0, 3.0 and 4.0. The four bets are: A–B at 2.0 × 3.0 = 6.0, A–C at 2.0 × 4.0 = 8.0, B–C at 3.0 × 4.0 = 12.0, and A–B–C at 2.0 × 3.0 × 4.0 = 24.0. If all three selections win, the punter collects £6 + £8 + £12 + £24 = £50 from a £4 total stake, a profit of £46. The treble alone returns £24 and outweighs the entire outlay; the doubles add the rest.

If two selections win and one loses, only the double that pairs the two winners settles. The other two doubles each contain the losing selection, so they lose. The treble contains the loser, so it loses. The punter collects from one double and is down on the other three lines. The minimum return on a two-winner outcome is the double that survives, multiplied by the unit stake; the maximum on this shape is the same single double, but the price on that double is the product of the two surviving legs.

If only one selection wins, all four bets lose, because every line in a Trixie has at least two legs. The punter loses the entire £4. If none win, the same.

The two-winner case is where the bet earns its keep. A treble punter on the same three picks would lose the whole stake if any single leg fell over. A Trixie punter still loses on a one-winner outcome, but walks away with a double on two winners and breaks even or better when the surviving double’s price is high enough to absorb the three losing lines. The shape is built for the case where one pick lets the punter down.

What the calculation looks like, from inputs to return

A worked payout. Three illustrative selections at fractional odds of 1/2 (1.50 decimal), evens (2.00) and 6/4 (2.50). Unit stake of £2 on each of the four Trixie lines, so the total outlay is £8. The four bets and their decimal prices are: A–B at 1.50 × 2.00 = 3.00, A–C at 1.50 × 2.50 = 3.75, B–C at 2.00 × 2.50 = 5.00, A–B–C at 1.50 × 2.00 × 2.50 = 7.50. If all three win, the four lines pay £6, £7.50, £10 and £15, a combined return of £38.50 from the £8 stake, for a profit of £30.50. If only A and C win, only the A–C double settles: £2 × 3.75 = £7.50 returned, leaving a net loss of £0.50 on the round. If only B and C win, the B–C double returns £10, a small profit of £2. If only one selection wins, the entire £8 is lost. The band on a two-winner outcome runs from a small net loss on the weakest double to a modest net profit on the strongest, depending on which two selections survive.

The result is a band, not a single figure, because the settlement depends on which two of the three selections win. The rule of thumb: any two-winner return clears the round only if the surviving double’s price is greater than the reciprocal of the payout share across the four lines. At the illustrative prices the strongest double (B–C at 5.00) clears the round by £2, the weakest (A–B at 3.00) leaves a £2 loss. A treble-winning outcome pays back several times the outlay regardless of which treble is in the price.

Bonuses, free bets and the Trixie — where it sits in the offer

A free bet is a token the bookmaker credits to an account and that can be staked like cash, with one structural rule: the stake is usually not paid back with a winning free-bet selection. A cash bonus, by contrast, is a credit added to the wallet, and the bonus amount is the part that gets played through; the deposit usually stays separate and the wagering is applied to the bonus only. A Trixie made entirely of free-bet lines is, in effect, four free bets that all have to clear the same condition at the same time. The asymmetry of the free-bet stake not returning with a win applies to every one of those four lines.

Bookmakers handle the eligibility of free bets on multiple bets in two ways. Some restrict the markets the free bet can be used on and exclude combination bets outright; that is the cleaner rule, and it removes the question of how a free-bet Trixie settles. Others allow free bets on combination bets but treat the stake as not returned, so the four free-bet Trixie lines each pay winnings-only when they hit. A free-bet Trixie that lands all three pays winnings on the treble plus winnings on the three doubles, but the four free-bet stakes are absorbed by the bookmaker rather than paid back.

A cash bonus behaves differently because the bonus is treated as the punter’s own money for staking. A Trixie staked with bonus funds counts the unit stake on every line against the wagering requirement, and the bonus and any winnings from it may become withdrawable only after the wagering is met. The wagering factor is the multiplier that decides how much betting the bonus takes: a £10 bonus at 10x needs £100 of qualifying bets before any withdrawal; a £10 bonus at 50x needs £500. The 10x ceiling on wagering is the current British cap under the 2026 bonus promotion rules, and it applies across the licensed market.

The wagering calculation is mechanical: turnover required equals the bonus base times the wagering factor, and the number of qualifying bets is the turnover divided by the stake on each. A £30 bonus at 10x, staked on Trixie lines of £5, requires £300 of qualifying bets, which is sixty Trixie lines at £5 each — fifteen Trixie rounds in full. The winnings on those fifteen rounds, less the £300 stake, are the net position before any of it becomes withdrawable.

Trixie strategies and what they actually cost the punter

A Trixie is sold as a forgiving bet because two of three legs can win and still pay. The arithmetic is colder. The Trixie punter pays for that forgiveness on every line: a Trixie at a unit stake of £1 costs £4 to enter against the £1 a straight treble costs, and the four-way structure is four separate margin lines rather than one. A bookmaker that prices the three legs honestly still takes its margin on each of the four combinations. A Trixie on three tight favourites, each at 1.30, prices the four lines at 1.69, 1.69, 1.69 and 2.20; the combined margin is the sum of the per-line margins, and the punter pays for the structure on top of the underlying margin on each leg.

Strategy 1: short-priced favourites. A Trixie on three short-priced picks is the most common pattern, and it is the most punished by the structure. The treble at 2.20 pays less than the punter expects because each leg’s price already carries a margin. The doubles compound the problem because two favourites at 1.30 each are unlikely to lose, and a 1.69 double returns £1.69 against a £1 stake, not enough to cover the other three lines. A Trixie of short favourites is a bet that pays out often and never by much; a single winner leaves the punter down £4.

Strategy 2: one anchor and two value picks. A Trixie built around a strong favourite and two longer-priced picks has a different shape. The two doubles that include the favourite pay modestly when the favourite wins and one of the value picks also wins; the favourite-with-value double is the only line that produces a meaningful return in a two-winner scenario, and only if the value pick wins. The treble pays well when all three land, and the long leg’s price is what carries the treble. The risk is that a single loss on either value pick collapses the bet to one double and a small return.

Strategy 3: hedging. A Trixie is a partial hedge against a straight treble: it gives back a double if one leg loses, where a treble gives back nothing. The trade is that the Trixie punter pays £4 to enter what the treble punter enters for £1, and the bookmaker’s margin across the four lines is wider than the margin on the single treble. Hedging is real; the cost of hedging is also real, and the punter pays the bookmaker for the option to recover on a one-loser scenario.

Strategy 4: same-game combinations. Some bookmakers price a Trixie on three selections from the same match. The four combinations all share at least one leg, and the correlation between selections — both teams to score and the favourite to win, for example — is a real feature. The bookmaker’s margin on same-game combinations tends to be higher than the margin on unrelated legs, and the punter pays for the correlation. A same-game Trixie is a structural bet with a structural price, and the punter should expect a less generous return on each line than on the same three picks priced as independent legs.

The Top 10 UK bookmakers for a Trixie bet

The ten bookmakers below hold a remote general betting standard licence from the Gambling Commission for real events. Each brand is a single entity on the Commission’s public register; where two brands share a licensee, the register shows the parent. The list is in the order research supplied, and the angle is the consequence: what each brand’s Trixie pricing and offer structure actually delivers to a punter who runs a Trixie through it.

NetBet — a wide price-boost list and a built-in Bet Builder

NetBet’s sportsbook is published under Gambling Commission account 39170, with the licence held by Netbet Enterprises Limited. The brand’s offer structure centres on daily price boosts, profit boosts and free bet offers, and the Bet Builder comes with dynamic odds that update the price as the punter adds or removes selections. For a Trixie punter, the Bet Builder matters because the same-game combinations in a Trixie can be built inside the builder, with the four combinations priced live as the picks change.

The NetBet sportsbook covers the major European leagues with stats from a built-in sports data feed, and the price-boost list runs daily. A Trixie built around boosted legs pays the boosted price, but the boost usually applies to singles and accumulators rather than to the doubles inside a Trixie, so the punter should check whether the boost carries over to the multiple combinations.

Verdict: a strong pick for a Trixie that includes same-game combinations, because the Bet Builder prices the four combinations live and the price-boost list runs deep. The Trixie punter pays the same margin on each line as on any other combination bet; the structural advantage is the builder.

QuinnBet — competitive prices, restricted free-bet markets

QuinnBet operates under Gambling Commission account 61011, with the licence held by QuinnBet (Gibraltar) Limited. The brand’s free bets are valid for seven days from credit and may be used on any market at fractional odds of 1/2 (1.50 decimal) or greater, with maximum odds of 50/1. Straight accumulators are allowed under those terms, but Trixies, Patents and Yankees are not. That single line is the entire free-bet story for a Trixie punter: the offer cannot be staked on a Trixie at QuinnBet.

For punter who fund the bet from their own cash, the price feed covers the main British and Irish sports and the in-play product runs across the same set of events. A cash Trixie settles normally on the four combinations, and the margin on each leg applies as on any other combination bet. The seven-day free-bet expiry and the 1/2 minimum-odds rule are the two terms a Trixie punter most needs to keep in mind if the offer is used on another bet type.

Verdict: a fair price for a cash-funded Trixie, and an outright block on free-bet Trixies. Anyone planning to clear a free bet on combination bets should pick a different brand from this list.

BetTom — straightforward welcome, modest bonus ceiling

BetTom operates under Gambling Commission account 64959, with the licence held by Bet Tom Limited. The brand’s sports welcome offer is half the qualifying stake back as a free bet, up to £50, with a matching half-stake back as free slot funds for the casino. The full terms apply to both halves; the cap is modest against the wider market. A Trixie punter is reading an offer that pays back half the first stake, with the free-bet half going onto a single bet and the slot-funds half going onto casino games, and the Trixie punter who uses the free-bet half on combination bets should check the brand’s terms.

For a Trixie punter, the relevant fact is that the offer is split across two products and the sportsbook half is a free bet, which means the stake is not paid back on a win. A free-bet Trixie at BetTom is four free bets whose stake is absorbed on each line; the offer is real but the structural rule is the same one any free-bet combination bet carries.

Verdict: a fair welcome offer against the wider licensed market, with the cap and the split between products worth weighing against bigger offers that put the whole ceiling onto the sportsbook.

Dabble — a peer-led product and a simple free-bet welcome

Dabble operates under Gambling Commission account 65677, with the licence held by Dabble Sports UK Ltd. The welcome offer is a £10 free bet on a first £10 deposit for new customers, with a seven-day free-bet expiry and the stake not returned on a winning free-bet selection. Minimum odds apply. The brand’s wider product is built around social features, with customers able to follow other punters and copy their bets, and the same social structure carries through to the in-play and pre-match markets.

For a Trixie punter, the welcome is a small one and the free-bet stake-not-returned rule applies. The minimum-odds threshold should be checked against the four Trixie lines: a free-bet Trixie at Dabble requires every leg to clear the minimum-odds threshold for the bet to qualify. The social features do not change the settlement arithmetic; they sit on top of it.

Verdict: a clean small welcome, and a Trixie-friendly bookmaker on price. The £10 free bet is a one-off that the punter either uses as four single free-bet Trixie lines or not at all.

BetUK — wide market coverage and a separate free-bet rule

BetUK operates under Gambling Commission account 39198, with the licence held by LeoVegas Gaming PLC. The free bets at BetUK exclude virtual sports, esports and non-UK/IE horse racing, and minimum odds apply. The market coverage runs across the major British and European sports with a separate casino product. The Trixie punter reading those free-bet rules gets a clear list of what the free bet cannot be staked on, and a Trixie built from real-event football or tennis markets is on solid ground.

The parent company, LeoVegas Gaming, also publishes the BetMGM UK product under the same Gambling Commission account, and a punter using one brand has the same identity-verification record as a punter using the other. The Trixie settlement is independent on each brand’s sportsbook.

Verdict: a real-event specialist whose free-bet exclusions are clear. A Trixie built from the major British sports settles without a free-bet conflict; a Trixie on virtuals or esports would.

DAZN Bet — in-play depth, conditional Cash Out

DAZN Bet operates under Gambling Commission account 48756, with the licence held by DZBT Limited. The brand offers Cash Out, a Bet Builder, daily bet boosts and an in-play product. Cash Out availability is not guaranteed and any bet stands if Cash Out is unavailable at the moment the punter asks for it. The in-play product is the centrepiece: the price feed updates as the event runs, and the Trixie punter placing four lines on a live event has to settle each line as it stands.

A Trixie is a poor fit for Cash Out. The four lines settle independently, and a partial cash-out on one line is the only way to take money off a Trixie mid-event, because the bet as a whole cannot be cashed out while one of the four combinations is still live. The Bet Builder and the daily boosts sit on top of the same price feed.

Verdict: an in-play specialist whose Cash Out is conditional. A Trixie punter looking for an in-play combination bet should expect a strong price feed and limited cash-out options on the multiple itself.

10bet — broad market and a clean licence trail

10bet operates under Gambling Commission account 43173, with the licence held by Blue Star Planet Limited. The sportsbook covers football, tennis and horse racing, with Cash Out, Bet Builder and Live Streaming available across the product. The licence trail is clear: the parent company name and the account number are both on the App Store listing and the brand’s own site, and a punter checking the Commission’s public register against either name finds the same record.

A Trixie punter reading 10bet’s product gets a working combination bet across the major British and European sports. The Live Streaming coverage is the differentiator: a Trixie built from in-running events can be watched on the same screen as the bet is settled, and the in-play price feed runs as a continuous update.

Verdict: a clean mid-market bookmaker with a strong in-play product. The Trixie punter looking for a Trixie that settles live gets a price feed and a streaming product, with a licence trail that holds up to a register check.

Tote — pool-betting heritage, fixed-odds sport

Tote operates under Gambling Commission account 54779, with the licence held by TDCO Limited. The brand is the legacy pool-betting operator, best known for horse and greyhound racing, and the fixed-odds sportsbook sits alongside the pool product. The Trixie punter using Tote’s fixed-odds product is using a separate settlement engine from the pool product, and the two do not share a wallet for the purpose of a combination bet.

The fixed-odds product covers the main British and Irish sports with a price feed that does not run to the same depth as a specialist sportsbook. A Trixie is on offer; the brand’s structural advantage is the pool product, which a Trixie punter would be using only as a side bet.

Verdict: a heritage brand with a working fixed-odds Trixie and a separate pool product. The Trixie punter looking for depth in the price feed would do better elsewhere; the punter looking for a heritage name with a clean licence is on solid ground.

Betfred — Bet Builder, Extra Places, racing depth

Betfred operates under Gambling Commission account 39544, with the licence held by Petfre (Gibraltar) Limited. The brand’s app features a Bet Builder, a Sub Switch feature that lets the punter swap one leg of a combination bet for another at the same price, Racing Post data inside the app, Extra Places on selected horse races, live casino and bingo. The combination bet product sits on top of a strong horse-racing feed.

The Trixie punter reading Betfred’s product gets a Bet Builder that can build the four Trixie combinations from a single event, a Sub Switch that can replace one leg of a settled Trixie if the replacement is at the same price, and a racing-heavy price feed for the horse-racing Trixie punter. The Bet Builder on football is the structural feature for the in-play Trixie punter; the Sub Switch is the structural feature for a Trixie where one leg’s price moves before kick-off.

Verdict: a strong pick for a Trixie that includes racing or football. The Bet Builder and the Sub Switch are real product features, and the price feed runs deep on the major British sports.

Fitzdares — premium positioning, ante-post racing depth

Fitzdares operates under Gambling Commission account 400, with the licence held by Fitzdares Limited. The brand positions itself as a premium bookmaker, with an app that offers Cash Out, accumulators, Lucky 15s, specials and ante-post markets on horse racing, football, tennis, rugby, cricket, golf and American football, with in-play live odds. The product is built around a small but high-quality set of markets, with ante-post racing as a centrepiece.

A Trixie at Fitzdares is a four-line combination bet on three of those markets, and the ante-post price on a horse racing Trixie pays the ante-post price across the four combinations, not the starting price. The Trixie punter reading the ante-post market should expect a lower payout on the racing combinations than on the day-of-race price, because the bookmaker’s margin on ante-post is wider to compensate for the non-runner risk.

Verdict: a premium bookmaker with a working Trixie and a deep ante-post racing product. The Trixie punter looking for a deep racing feed is well-served; the punter looking for a generic price across all sports would find a smaller product here than at the wider-market brands.

Odds and how to read what the bookmaker is keeping

Every price on a Trixie carries the bookmaker’s margin, and the margin is what the punter pays to enter the bet. The way to see it is to look at the implied probability of a single outcome: a price of 2.00 implies a 50% chance, a price of 4.00 implies a 25% chance, and the sum of implied probabilities across all outcomes of a market is the overround. A perfectly fair market with no margin has an overround of exactly 100%; a market with a 5% margin has an overround of 105%, and the bookmaker keeps 5% of every unit staked on the market across outcomes, on average.

A Trixie’s margin is the sum of the per-leg margins applied across the four combinations. A bookmaker that prices each leg of a Trixie at a 5% margin builds the four combinations at a compounded margin that is closer to 20% across the bet, and the punter pays the bookmaker for the privilege of combining the legs. The structural margin on combination bets is wider than on singles, and the wider the structure, the more the bookmaker keeps.

The decimal form of the odds makes the calculation visible. Three legs at 2.00, 3.00 and 4.00 imply 50%, 33.3% and 25% probabilities, and the sum is 108.3% — an overround of 8.3% across the three singles. The Trixie’s four combinations, with their implied probabilities, sum to a higher number still, and the gap between the sum and 100% is the Trixie’s overround. The punter reading a Trixie price should treat the headline odds on each leg as the starting point and the combinations as a separate pricing exercise.

The legal frame in Great Britain

A bookmaker serving customers in Great Britain needs a Gambling Commission licence wherever it is based, under sections 33 and 36 of the Gambling Act 2005 as amended by the Gambling (Licensing and Advertising) Act 2014. The Commission’s public register is the only test of who holds one; a brand can use a .com or a .co.uk domain and the domain proves nothing. A Gibraltar, Malta or Curaçao licence is not a substitute for a Commission licence at the point of consumption.

There is no statutory list of permitted bets or markets. An operator holds a licence for a category — remote general betting standard (real events), remote general betting standard (virtual events), remote general betting limited, remote pool betting, remote betting intermediary — and offers markets under its own rules and the Licence Conditions and Codes of Practice. A Trixie is a combination bet on real events, and it is offered by every bookmaker on the Commission’s remote general betting standard (real events) register.

Minimum age 18, and identity is verified before the first deposit. The credit card ban for gambling in Great Britain (in force since 14 April 2020) covers credit-card-funded payments through an e-wallet. The player pays no tax on betting winnings in Great Britain; General Betting Duty is the operator’s tax on gross profits.

The bonus rules in force this year

The promotion rules in force since 19 January 2026 cap wagering requirements on bonuses at 10x, and they ban mixed-product promotions that require gambling on two or more product types such as betting, casino, bingo and lottery. A £10 bonus at 50x needs £500 of qualifying bets; under the cap, no more than £100 of qualifying bets are required. The cap applies to wagering requirements; whether it applies to free bets with no wagering condition, and any cap on the money value of a bonus, are not established in the published rules.

The 10x cap is the ceiling across the licensed British market. A punter reading a welcome offer at any of the ten bookmakers above is reading an offer that is compliant with that cap, and the punter comparing offers should compare the underlying bonus size and the bonus base against the cap rather than against a market-wide percentage.

Responsible gambling and the Trixie punter

GAMSTOP is the national multi-operator online self-exclusion scheme and a mandatory licence condition for online operators since 31 March 2020. Self-exclusion periods run six months, one year, five years, or five years with auto-renewal, and after the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. GAMSTOP covers online sites and apps; betting shops use a separate service.

A financial vulnerability check (LCCP condition 3.4.4, in force since 30 August 2024) applies to licensed remote betting when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days, and the threshold is currently in force (since 28 February 2025). The check is a public-record check — bankruptcy or county court judgments, for example — not an income check or a credit reference check. Financial risk assessments, the “affordability checks” of the press, are announced in a staged plan with no start date; the published framing is “announced, staged, no start date”, not “in force”.

Deposit limits under RTS 12 require operators to offer a gross deposit limit on a fixed time frame. The first changes have applied since 31 October 2025, a second phase was postponed to 30 September 2026, and whether that second phase is live is not established. There is no state-set deposit or loss ceiling; limits are the customer’s choice. Help: GamCare (the National Gambling Helpline), GambleAware, NHS gambling clinics, Gamblers Anonymous. The Trixie punter reading this page is reading it because they are considering the bet; the help lines are the resource if the bet stops being a choice.

The offshore picture

A GB licence is compulsory at the point of consumption. Providing gambling facilities in Great Britain without the licence the Act requires is an offence under section 33 of the Gambling Act 2005, aimed at the operator. No offence aimed at a customer who merely bets on an unlicensed site was found in the Act: the customer’s loss is the loss of the protections a licence brings.

An unlicensed brand offers no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body and no British consumer redress if funds are withheld. The 10x bonus cap, the £150 financial vulnerability check and the other consumer protections are not binding on an unlicensed operator, and a customer who has self-excluded through GAMSTOP can still reach an unlicensed site. The honest framing is that licensed = checks, limits, GAMSTOP, the bonus cap, and identity verification before the first bet; unlicensed = none of those protections and possible loss of funds. Neither is “the safe choice” by default.

Frequently asked questions

What is a Trixie bet?

A Trixie is a multiple bet on three selections, made up of four separate wagers: three doubles covering each pair of selections and one treble covering all three. A unit stake is placed on each of the four bets, and the total outlay is four times the unit stake. The bet is offered by every UK-licensed remote bookmaker on its real-events sportsbook and settles using the same combination logic as any other multiple.

How does a Trixie bet work?

The bookmaker takes three selections, builds the three doubles and the one treble from those selections, and stakes the unit stake on each. The bet pays out on a three-winner outcome from all four lines, on a two-winner outcome from the single surviving double, and loses the entire stake on a one-winner or zero-winner outcome. The shape is built for the two-winner scenario: a treble would return nothing if one leg fell over, but a Trixie still pays back the surviving double.

Whats a Trixie bet in plain terms?

Three picks, four lines, the same stake on each. The punter pays four unit stakes to enter and the bookmaker pays back from the winning combinations. The Trixie is the smallest of the full-cover bets and the most popular because it gives back on a two-winner outcome while still pricing the treble for the all-three-winners scenario.

How can it be checked that a bookmaker holds a Gambling Commission licence?

The Commission’s public register at the regulator’s site can be searched by business name, trading name, domain or account number, and the record shows the licence categories and the licence holder. A brand that does not appear on the register is not GB-licensed; a brand that does appear is licensed for the categories the record lists. The register is the only test of who holds a licence; the domain (whether .com or .co.uk) does not prove a licence.

How is the return on a bet worked out from the stake and the odds?

The return on a single is the stake multiplied by the decimal odds. The return on a double is the stake multiplied by the product of the two legs’ decimal odds. The return on a treble is the stake multiplied by the product of the three legs’ decimal odds. The profit is the return minus the stake across all the lines that settle. A Trixie’s return is the sum of the four line returns across the combinations that win.

What is the bookmaker’s margin and how can it be seen in the odds?

The margin is the share of every unit staked that the bookmaker keeps on average. It is the difference between 100% and the sum of the implied probabilities across all outcomes of a market, where each implied probability is the reciprocal of the decimal odds. A market with a margin of 5% has an overround of 105%, and the bookmaker keeps 5% of every unit staked across outcomes. A Trixie’s margin is the sum of the per-leg margins across the four combinations, and the combined margin is wider than the margin on a single because the combinations compound the underlying margin.
